Spied: Audi R8 Spyder

The Audi R8 Spyder has been revealed in almost finished form in these latest spy shots from the Nurburgring. If it weren't for the matt black paintwork, this convertible R8 mule could be the production ready car.

Our first look at this prototype model confirms that it will use a traditional fabric roof, rather than a targa panele, which should help save weight.

The engine cover's been redesigned and the fuel filler cap has been moved from the B-pillar to the rear quarter panel to allow for the drop-top arrangement.

However, the standard R8's 4.2-litre V8 with 414bhp should remain unchanged for the convertible. Its performance figures will also be very similar to the R8 coupe's too, so expect a 0-62mph time of around four seconds and a top speed around 180mph.

A V10-powered version of the R8 coupe is expected to make its debut early next year, and it's likely that this more powerful engine will be used in the convertible model in the future.

The V8-engined R8 Spyder should hit the showrooms in mid-2009 and cost around £85,000.
